Pop superstar Rihanna is being sued for more than £70,000 by a business in a row over the bill for her grandmother’s funeral.

The Umbrella singer ­arranged a lavish send-off when Clara “Dolly” Braithwaite died of lung cancer in her ­native Barbados.

But more than a year later the star, 25, is being ­accused of only paying £22,000 of the £94,000 cost she was billed.

Funeral directors Downes and Wilson have lodged a civil suit in the High Court in Barbados in her real name Robyn Rihanna Fenty demanding the rest of the money. Rihanna’s lawyers insist she does not owe it.

The funeral home reportedly conducted the church service and all burial arrangements, which included retrofitting the Emmanuel Baptist Church in St Michael, buying the grave at Coral Ridge Memorial Gardens in Christ Church.

The funeral had included tents, limousines giant screens and ­exotic flower arrangements.

Earlier this year Rihanna won a £3.3million High Court battle against fashion giant Topshop for selling a T-shirt emblazoned with her photograph.

When contacted by the Sunday People on Friday Barbados legal firm James Wilson and Company, representing the funeral home, said: “We will not be making any further comment.”
